Application filed November $27, 1931. Serial No..577,526.

This invention relates, generally, to lubrieating devices; and the inventionhas reference, more partlcularly, tea-novel lubrlcator for lubricating elevator guiderails.

Elevator guide rail lubricators as hereto-v fore commonly constructed, usually employ either a capillary or gravity, oracombined capillary and gravity feed of the lubricant to the guide rails. Various means are used on these lubricators for regulatingthe feed of the lubricant to the guide rails. The great majority of these lubricators have not proven entirely satisfactory in use because of various inherent defects, among which may be men-.

cause such oils cannotbe fed by capillary attraction and yet heavy oils are desirable for guide rails because of the tendency of. the same to remain on the rails, and not to run ch" as is the case with the light oils commonly used in capillary lubricators. These lubricators are also objectionable because changes in temperature eiiect the rate at which the-oil is fed so that these lubricatorshave a tend ency of either feeding the lubricant too rapidly or not rapid enough.

Both the capillary and the gravity types of lubricators are also objectionable because they ofttimes supply lubricant to the guide rails whether or not the elevator car is in operation, so that considerable lubricant is therefore wasted. Force feed lubricators, employing a mechanical or metal driving connection with the elevator guide rails, have not become popular because of'the tendency of the same to scratch or score the rails as well as being noisy in use.

The principal ob ect' of the present inven 7 tion is to provide a novel guide raillubricator which is adapted .to be carried by a movable,

part of the elevatorsystem, such as the car or counterweight, and which automatically supplies lubricant, inpredetermined quantities, all long the length of the guide rails while the elevator is in operation, the said lubricator "operating to automatically stopthe supply of lubricant during idle periods of the elevator.

Another object of the present invention lies in the provision of a novel guide rail lubricator which is adapted to handle heavy oil as well as light oil, and which operates to positively supply lubricant to the desired surfaces, the said lubricator having means for same is kept mobile and is fed in the desired quantityregardless of temperature changes.

Still another object of the present invention is to provide a novel guide rail lubri' cator which is adapted for; use on all types of elevator installations whether high or low rise, or high or low speed, the said lubricator being of simple, rugged construction and having an exceedingly long life in use.

A fourth object of the present invention lies in the provision of a novel guide rail lubricator which is operated, by cushioned, frictional contact with the guide rail, to mechanically pick-up and deliver lubricant to the guide rail,the said lubricator being non-inj urious to the guide rail or other parts of the elevator system, the same eliminating metal to metal driving contact with the guide rail as well as capillary action, and being adjustable to supply only the desired quan-' .tity of lubricant without waste or splashing.

agitating the stored lubricant whereby the clearly understood from the following de-" tailed description of the same.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts.

Referring now to Figs. 1 to 5 of the drawings, wherein the preferred embodiment of the invention is illustrated, the reference numeral 1 designates an elevator guide rail along which a guide shoe 2 is adapted to move, which guide shoe may be mounted, for example, upon either an elevator car or a counterweight. g V

The novel lubricator of this invention is designated as a whole by the reference numeral 3 and is mounted upon the guide shoe 2 for moving up and down the hatchway. Lubricator '3 comprises a frame member 4 which is of substantiallyC-shape in side elevation. Frame member 4 is provided at its bottom-with outwardly extending transverse lugs 5 having slots 6 therein adapted to receive screws 7 that are-threaded into the upper portion of the guide shoe 2 and serve to attach the lubricator to this guide shoe. The slots 6 permit adjustment of the frame member 4, with respect to guide shoe 2, so that this frame member may be adjusted toward or'away from the guide rail 1.

The frame member 4 has a substantially- U-shaped or channel cross-section consisting of side flanges 10 and a connecting web or outer Wall 11. The outer wall 11 is cutout or recessed at the top and bottom of the frame member, as indicated at 8 and 8, respectively, to accommodate the guide rail 1. The side flanges 10 adjacent the top of the frame member 4 are provided with oppositely directed, outwardly extending, transverse bosses 12. Bosses 12 and side flanges 10 have mutually aligned circular apertures for receiving bolts 13. Bolts 13 extend through the apertures of bosses 12 and flanges 10, and'serve to pivotally support the upper end portions of a pair of links 14 disposed at opposite sides of the frame member 4.

Links 14 incline downwardly from the pivotal bolts 13and are pivotally connected at their lower end portions to trunnions 15 projecting outwardly from the ends of a hollow lubricant drum 16. Links 14 serve to support the lubricant drum 16 from the bolts13 and, in use, this drum is adapted to turn about its pivotal connection with links 14. The central portion 17 of this drum is positioned Within the interior of frame member 4, whereas the end portions 18 and 19 of this drum project outwardly beyond the sides of the frame member 4 somewhat. These end portions are'illustrated as having their circumferential outer surfaces beveled or inclined (Fig. 2) so that in the event any lubricant falls upon these surfaces, such lubricant will be conveyed by centrifugal action to the central portion 17 of the drum, from whence such lubricant will fall into the channel-shaped interior of frame member 4 to be conveyed to the surface of the guide rail 1. The drum end portions 18 and 19 are provided with filling plugs 21 to enable the insertion of lubricant 22 into the hollow interior of the drum.

A hollow fitting or nipple 23 is threaded into an aperture provided in the central portion 17 of drum 16, and is positioned on that side of the drum which is opposite to the flll ing plugs 21. The fitting 23 is provided with a transverse aperture 24 communicating with he hollow interior of this fitting.

A tube 25 is threaded into the hollow interior of fitting 23 and extends diametrically within the interior of drum 16 for the greater portion of the width of this drum. The free end portion of tube 25 is provided with diametrically opposed apertures or slots 26. A cap or closure member 27 of cup shape overlies the free end portion or tube 25 and a transverse pin 28, carried by this closure member, extends through the slots 26 and serves to thereby retain the closure member in assembled relation upon the tube 25, while permitting relative sliding movement of the closure member upon the tube end portion.

When the drum 16 is turned so that the free end portion of tube 25 extends down wardly within this drum, as shown in Fig. 4, the closure cap 27 moves downwardly and outwardly of tube 25, thereby uncovering the slots 26 permitting lubricant to enter the interior of tube 25 through these slots. Vfhcn the drum 16 is turned so that the free end portion of tube 25 extends upwardly within thisv drum, as shown in Figs. 1 and 3, the closure cap 27 moves downwardly and over the top end portion to thereby completely close the slots 26.

A regulating plug 29 is threaded radially inwardly into the hollow interior of fitting 23 and is adapted to be adjusted toward or Tax end portion of tube 25 is conveyed, in use,

to the hollow interior of fitting 23 from whence such lubricant flows through the transverse aperture 24 and into the channelshaped interior of frame'member 4,.which conveys such lubricant to the top of guide shoe 2 for lubricating the guide rail. The inner surface of the wall 11 of the frame member 4 is illustrated as provided with lubricant conveying grooves 30 for facilitating the flow of the lubricant from the interior of the frame member onto all operating surfaces of the guiderail 1. By threading plug 29 inwardly of fitting 23, this plug may be caused to either partially or wholly obstruct the transverse aperture 24. Thus, the plug 29 serves as a means for regulating the rate at which lubricant will flow from tube 25 through aperture 24 into the interior of the frame member and from thence to the guide shoe 2.

The central portion 17 of drum 16 is formed with enlargements or projections 31 and 31 adjacent opposite sides of the fitting 23, which projections provide flat surfaces 32 and 32 for receiving the end portions of a band or strip of suitable frictional material 33. The frictional material 33 is preferably of a fibrous nature and may consist of a strip of brake lining. The band 33 extends around the exterior surface of the central portion 17 of the drum 16 and has its end portions secured to the projections 31 and 31 as by screws 34. The cylindrical wall of the drum opposite to the projections 31, 31 and fitting 23 is preferably thickened as shown at 35, so that this thickened area, together with plugs 21, will act to counterbalance the weight of the projections 31, 31 and fitting 23, whereby the drum 16 is substantially dynamically balanced and will turn freely about its pivotal support upon the links 14. Owing to the inclination of the links 14 and to the weight of the drum 16, this drum tends to move toward the guide rail 1 so that the band 33 always presses somewhat against the surface of the guide rail. The frictional engagement thus created between the guide rail and the band 33 is sufficient to cause the turning of the drum l6 about its pivotal connection with links 14 when the guide shoe 2 moves up and down the hatchway.

In operation, assuming the car has moved down to the bottom of the hatchway, the drum 16 will be in the position shown in Figs. 1 to 3, with that end portion of the band 33 overlying the flattened surface 32 abutting the guide rail 1. lViththe drum 16 in this position, any lubricant within tube 25 will tend to flow out through aperture 24 into the interior of frame member 4 to be conr veyed by grooves 30 to the guide rail surfaces.

Since the closure cap member 27 is in closed position,-with respect to slots 26, no lubricant can flow from the drum into the tube 25 so that regardless of how long the car remains stationary, only the limited quantity of lubricant within tube 25 can drain onto the guide rail. Thus, when the car is idle, as durin the night period, there is no waste of lubricant.

Assuming that the car or counterweight carrying the guide shoe 2 starts to move upwardly, the frictional engagement between the band'33 and the guide rail 1 will cause drum 16 to revolve in a counter-clockwise direction, as viewed in Figs. 1 and 4. As the drum 16 commences to revolve, the end portion of the band 33 overlying the fiat surface 32, inovcs counter-clockwise away from the guide rail surface and successive portions ofithe band 33 progressively roll over the guide rail, as especially shown in Fig. 4. Continued rolling movement of the drum 16 causes the free end portion of tube 25 to turn downwardly within this drum, result ing in closure cap 27 moving downwardly under the influence of gravity, thereby uncovering slots 26 so that a quantity of lubricant is caused to enter the interior of tube 25, as shown in Fig. 4. Continued rolling movement of the drum finally causes'that end portion of band 33 overlying the fiat surface 32 to move into abutting relation with the guide rail 1, whereupon the turningmovement of the drum 16 ceases, and thereafter the end portion of the'band 33 overlying the surface 32 merely slides along the guide rail.

When the upward movement of guide shoe 2 comes to a stop, the end portion of the band overlying surface 32 remains in abutting relation to the guide rail but as soon as the guide shoe starts to descend,'the drum again rolls on the guide rail surface, but in a clockwise direction, as shown in Fig. 5; The continued rolling movement of the drum causes the free end portion of tube 25 to move, upwardly, whereas the fitting 23 moves downwardly, so that the lubricant contained within tube 25 tends to flow outwardly of fitting 23 and into the interior of the frame member 4 to be conveyed to the guide rail surfaces. It will be noted that the lubricant within tube 25 is forced outwardly through aperture 24 in fitting 23, partially by the action of centrifugal force, partially by gravity once the fitting 23 has moved below a horizontal position, and also by the pressure created by closure member 27 in sliding radially inwardly over tube 25, as suggested in Fig. 5. A too rapid out-i'low of the lubricant within tube 25 is prevented, however, by the action of closure cap 27 which serves to close apertures 26 in the tube 25 when this tube moves into the position shown in Fig. 5, so that the upper portion of the tube, becoming air bound, acts to resist the flow of lubricant out of the aperture 24. i r 1 It will thus be noted that the drum 16 does not turn continuously while the guide shoe is movin up and down the hatchway, but merely makes a major part of a revolution and thereafter comes to rest within one of the flattened end portions of the band 33 sliding over the surface of the guide rail. Inasmuch as the pressure between such flattened end portions of the band and the guide rail is relatively slight per unit area, practically no wear of the band takes place and the band serves to spread lubricant along the edge of the guide rail. Any slight wear of band 33 which may take place is automatically compensated for by links 14 which permit the drum 16 to move closer to the guide rail to take up such wear.

By adjusting regulating plug 29 in or out of the fitting 23, the rate at which lubricant is discharged from the interior of tube 25 may be controlled to a nicety, thereby providing for the requirements of any particular installation. The outer wall 11 of the frame member is provided with an aperture 37 providing access to'the regulating plug 29.

Thus, it is possible, by adjusting the plug 29, to obtain a very exact control of the supply of lubricant to the guide rails, thereby eliminating waste of lubricant and splashing or draining of the same into the hatchway. Inasmuch as the lubricant within the drum is agitated at each reversal of direction of the guide shoe, the same is kept in a mobile state regardless of temperature conditions and is caused to feed into tube 25 under all circumstances. Thus, it is possible to use relatively heavy oils in drum 16 and obtain entirely satisfactory feeding of the lubricant owing to the positive actuation of the same and to the scooping action of tube 25 in passing through the lubricant. The closure cap 27 not only serves as a valve to limit the flow of lubricant into tube 25, but this closure cap acts, when in the upper portion of its movement, by slidin downwardly over the end portion of tube 25, to close apertures 26 and create a slight increase in air pressure in tube 25 above the lubricant therein to thereby exert pressure upon the lubricant within the tube 25 and effect the forceful ejection of the lubricant outwardly of this tube through the aperture in the fitting 2.3.

Inasmuch as only the band of cushioning material comes in contact with the guide rail, the lubricator is extremely quiet in use. vSince the free end portion of the tube 25 dips down into the lubricant 22, during the period when lubricant is passing into the interior of tube 25, the said tube acts to utilize substantially all the lubricant within the reservoir before the latter needs refilling. Thus, the lubricator maybe used for long periods wtihout the necessity of inserting new lubricant ther-einto, especially since there is no waste of lubricant.

In the form of the invention shown in Figs. 6 to 10, the lubricant is contained within a substantially rectangular casing 38. Casing 38 is provided with lugs 36 at the bottom thereof, which lugs have slots 6 therein for receiving screws 7 for attaching the casing to the top of the guide shoe 2. Slots 6 enable the adjustment of casing 38 toward and away from the guide rail 1. Casing 38 is provided with a removable cover 39. The highest lubricant level 49 within casing 38 is fixed, when filling this casing, by an aperture 41 provided in the end wall of the casing 38. A shaft 42 extends transversely of casing 38 and has its end portions retained within apertures provided in the side walls of this casing as by means of pins 43. A pair of spaced links 44 are pivotally mounted upon the shaft 42 and incline upwardly therefrom. The upper end portions of links 44 carry a transverse pivotal pin 45 which in turn pivotally supports a drum 46, somewhat similar in shape to drum 16.

Drum 46 is provided with annular flanges 47 at its sides, which flanges project through an aperture 48 provided in the end wall of casing 38 and in the end wall of cover 39 for overlying the sides of the guide rail, though spaced somewhat therefrom. A band 52 extends round drum 46 and between flanges 47, which band is similar to band 33 described in connection with the preceding figures. Owing to the inclination of links 44, the band 52 is always pressed somewhat against the guide rail. A pair of continuous flexible ropes 49, preferably of fibrous material, are mounted upon the band 33 and are positioned adjacent the respective flanges 47 for ext-ending between these flanges and the sides of the guide rail, whereby said ropes rub slightly against the sides of the guide rail 1 in use, as especially shown in Fig. 8. Flexible ropes 49 extend downwardly into the lubricant within casing 38 and serve in use to raise lubricant to the guide rail. The drum 46 is provided with a radial enlargement 50 having flattened surfaces 51 and 51 at its sides for respectively receiving the end portions of band 52, which end portions are secured to surfaces 51 and 51 as by screws The wall of drum 46 is thickened at 53 opposite to the enlar ement 50 so that this drum will e dynamically balanced upon the pivotal pin 45 and will freely turn thereon.

In use, owing to the frictional engagement of the band 52 upon the surface o the guide rail 1, as the car or counterw carrying the guide shoe 2, commences to move up or down the hatchway, the drum 46 is turned or oscillated in the same manner as the drum 16 in the preceding figures. The end portions of band 52, overlying flatten-ed stop surfaces 51 and 51 by contacting with the guide rail, serve to limit the turning movement of the drum 46 in either direction of rotation. Figs.

9 and 10 are views corresponding .to'Figs. 4t and 5 of the previously described structure and show the operation of this modified form of the lubricator. Each time the guide shoe 2 reverses 1ts direction of motlon, the drum 46 turns through the ma or pOltlOIlOf a revolution in onedirection or the other, de

pending on the direction of movement of the guide shoe, causing the ropes 49 "to pick-up lubricant from within the-casing 38 and to convey the same to the surfaces of the guide rail. The fibrous band 52 absorbs lubricant from the ropes 49 and also acts to apply lubricant to the guide rail. It will benoted that the ropes 49 do not depend upon capillary action to remove lubricant from reservoir or casing 38, but instead positively lift the lubricant from this casing and apply the same to the guide rail, insuring the proper lubrication of the latter. i i
